Down Syndrome
What a difference an extra chromosome can make. Here we explore the misconceptions -- as well as the ups and downs -- of Down Syndrome, a congenital genetic disorder that is caused by the presence of an extra 21st chromosome. The affected person is mildly to moderately handicapped, short in stature, and has a flattened facial profile.

How many babies with Down syndrome are born daily in the US?
About 14 babies a day, which is approximately 5,000 a year in the US.
More parents are choosing now to have their Down baby born, rather than terminate the pregnancy, due to better health care and social programs, and disabilities are more accepted now in our society.
How many cases have been recorded of a mother with Down syndrome giving birth to a normal baby?
The real answer can't really be known but this is a good article which discusses the subject somewhat. It is really rare that a woman with down syndrome gives birth ever because of the genetic problems, but it does happen.

World-wide, over 5.8 million people have Down syndrome. (This condition affects people of all ages, races, religions and economic situations.)
Approximately 1 in every 1,000 babies has Down syndrome.
In the UK
It is estimated that there are about 60,000 people with Down syndrome living in the UK. About 600 babies with Down syndrome are born in the UK each year.Do you capitalize the words 'down syndrome'?
As to whether the word "syndrome" should be capitalized, there seems to be no final word on that. Various dictionaries and encyclopedias seem to have different styles.
Answers.com goes for the option of spelling it like this: "Down syndrome."

What would a Eugenicist say about Down syndrome?
Eugenics is the science (or perhaps the philosophy) of proactively guiding the development of the human genome. This can take the form of a whole spectrum of activities, from genetic testing and counseling of couples, to even selective termination of pregnancies.
Down's syndrome is among the more easily identified genetic disorders; simple genetic testing can detect it readily, since sufferers have an extra 47th chromosome, whereas all other humans (ranging from normalcy to even catastrophically disordered) will only have 46 chromosomes in 23 pairs.
A Eugenicist would likely counsel couples with a history of genetic abnormalities to consider alternate means of conception, for example in-vitro fertilization using a donor egg or sperm, as appropriate, to eliminate the genome of a parent with a history of such defects. Couples with equally high risk factors for such genetic abnormalities may be counseled to adopt or conceive using others' gametes entirely. A Eugenicist, depending on their particular philosophical leaning, may even counsel the termination of a pregnancy if testing reveals Down's Syndrome or another birth defect.

Who is the oldest female in the US with Down syndrome?
I do not have real-time data to provide the name of the oldest female in the US with Down syndrome. You may be able to find this information through research or by contacting organizations that focus on Down syndrome advocacy and support.
Do you feel this is true? Have you watched people? Many people appear to be needy and have a rough exterior, but that could in fact be brilliant and self-sufficient. There are so many variables to consider when it comes to a subject like this.
Can animals have down sydrome?
Im not sure animals can actually have down syndrome, but they can always have birth disorders. Although there is also one recorded case of a cat believed to have down syndrome.

When can Down Syndrome be detected?
A new test has been developed, called FASTER (First and Second Trimester Evaluation Risk), with which Down syndrome will be able to be detected during the first trimester of the pregnancy - about 11 weeks after conception - with 87% accuracy.
Does Robin Thicke son have downs syndrome?
No, Robin Thicke's son Julian does not have Down syndrome and was not born with any mental or physical disabilities.
Does Jane Lynch have a sister in real life who have Down Syndrome?
Lane Lynch does not have a sister in real life who has down syndrome. Her character on Glee has an older sister with down syndrome.
Causes of Klinefelter Syndrome
The additional sex chromosomes in men with Klinefelter syndrome results from nondisjunction during meiosis and may have a paternal (50 to 60 percent) or maternal (40 to 50 percent) origin. This contrasts with Down syndrome, which is caused predominantly by maternal nondisjunction and inheritance of the extra chromosome 21 from the mother.
How do you receive down syndrome?
The cause of downs syndrome is a process called disjunction.In this process the two copies of chromosomes 21 fail to separate during the formation of egg, resulting in the formation of egg having two copies of chromosome 21.. when this egg gets fertilzed, the resulting baby ends up havng three copies of chromosome 21 in each cell... however the cause for this disjunction is not known...

What is the most common treatment for nerve entrapment syndrome?
Rest and splinting are effective treatments for entrapment syndromes.
Do Down syndrome children always have ginger hair?
No, not at all. I know a few people with Down syndrome, and none of them actually has ginger hair.
Where did down syndrome come from?
Downs syndrome is a genetic abnormality caused by an extra chromosome, in simple terms - as a healthy individual you inherit 22 chromosomes from your mother and 22 from your father, so that's 44 altogether, 1 chromosome from each of your parents will combine to form 22 sets, in a person with Downs syndrome there is an extra abnormally shaped set of chromosomes. So in short a person with Downs syndrome has 23 chromosomes instead of 22.
Does the man age determine downs syndrome?
No, not the father. But older mothers have a higher rate of bearing a child with Down syndrome.

When is the year when down syndrome was discovered?
In 1959 the cause of Down Syndrome was discovered to be due to the trisomy 21. Down syndrome or trisomy 21 was first described by the british doctor John Langdon Down in 1866 and also happens to be named after him.
Why would you need to check an unborn baby for Down syndrome?
Because some doesn't want to keep it if it has it. It is not like raising a ordinary child but this one will have special needs.
Can downsydrome be detected before birth?
Down syndrome in a baby can be identified with amniocentesis during pregnancy or at birth. See more in related link.
Amniocentesis is a procedure performed on pregnant women to determine possible risk factors with their developing fetus. A long needle is inserted through the abdomen into the uterus, being guided by an ultrasound, that extracts amniotic fluid. This amniotic fluid is then further tested to determine certain risks such as Down syndrome. Although amniocentesis does have it benefits of obtaining this kind of knowledge, it also poses threats to the fetus such as a .8% chance of miscarriage, clubfeet, trauma to the mother, preterm labor and an infection of the uterus.
According to an article published in a Canadian journal, a study in Canada showed that amniocentesis performed between weeks 11 and 13, resulted in 29 out of 4,374 women gave birth to children with clubfeet. Because of this risk, doctors generally try to avoid performing amniocentesis before week 15 of pregnancy.
A safer diagnosis of Down syndrome would be through blood screenings. The mother's blood must be drawn then the sample will be sent to a lab for further testing and possible diagnosis. The first screening is generally done between weeks 11 and 13. A second screening is done between week 15 and 20 of the pregnancy. According to the March of Dimes, karyotyping done through prenatal blood screenings cannot diagnose syndrome of the fetus but they can show whether or not the risk is high or low. Although karyoptying is not as accurate as amniocentesis, it is less invasive and poses no harm to the mother or the fetus.
Why do many people with Down syndrome look somewhat alike?
Because Down Syndrome causes certain physical changes that we notice more than the person underneath. Down children all resemble each other because of the effects of the disorder, but they do not all look the same.
